There is a long "whizzing" noise coming from an "air pump" right next to the hood positive terminal for jumping on my 97 328i. The noise would last for approximately 2-3 minutes at cold startup then stop completely. What is that pump or whatever that is called? Any help would be greatly appreciated. Thanks,
